1.3

Battery management

• Operates from a three cell NiCd/NiMH or a one cell

Li-ion battery pack

• Battery Voltage Monitor (BVM) to detect a too low main

battery voltage with programmable threshold levels.

A low battery condition is reported via the interrupt

mechanism.

• Charger control. There is an option between two

different charger control functions, depending on the

configuration:

– Configuration Constant Current Constant Voltage

(CCCV). Linear charger control supporting Li-ion as

well as NiCd/NiMH battery types for a wide range of

battery capacities.

– Configuration BATMAX comparator that compares

the battery voltage against a programmable

threshold voltage. This function can be activated by

software and is used to detect the end-of-charge.

• Supports the use of a backup battery that powers at

empty main battery situations. The backup battery is

used to supply the RTC, the internal state and the

LPVDD supply in it’s ECO mode. Goldcaps, Li and Li-ion

cells are supported.

• Includes a Backup Battery Charger (BBC).

A rechargeable backup battery or backup capacitor can

be charged from the main battery. For charging, a

programmable constant voltage mode is supported.

1.4

Subscriber identity module card interface

• Two different modes that can be selected with the

Subscriber Identity Module card Interface (SIMI):

– Transparent interface including an arbiter and signal

level translators

– Subscriber Identity Module (SIM) card interface with

integrated sequencer, arbiter and signal level

translators. The sequencer supports and controls

card activation and de-activation, warm reset and

controlled clock stop for power-down modes.

• Dedicated SIM supply (SIMREG). Supports

3.0 V and 1.8 V cards, including a power saving ECO

mode for the power-down mode of the SIM card.

• Enhanced ESD protection on all pins that connect to the

SIM card contact pins.

APPLICATIONS

• Mobile phones.

GENERAL DESCRIPTION

The PCF50603 is a highly integrated solution for power

supply generation, battery management including

charging and a SIM card interface including supply

generation. The device is controlled by a host controller via

a 400 kHz I2C-bus serial interface.
